Abstract (en)

[origin: GB2328160A] A lower limb prosthesis comprises a knee flexion control device (18) arranged to resist flexion at the knee joint both hydraulically and pneumatically by means of a dual piston and cylinder assembly (18A, 18B, 18C, 18D, 18E). The resistance to flexion is arranged by electronic control means (which are programmable) via needle valve (18H) and rotary valve (180) and stepper motors (20, 22) to be predominantly hydraulic (18H) during the stance phase and predominatly pneumatic (180) during the swing phase of the walking cycle. The electronic control means are furthermore responsive to sensing means (26A, 26B, and 28) so as to automatically adjust flexion resistance according to the activity mode of the amputee. A further invention comprises an hydraulic knee flexion control device.
